EYEGLASS-MOUNTING.

Specification of Letters Patent.

Patented Apr. 2,1918.

Application filed November 18, 1916. Serial No. 132,000.

To all whom it may concern:

Be it known that I, 'WALTER A. GoATns, a citizen of the United States, and resident of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improve ments in Eyeglass-Mountings, of which the following is a specification.

This invention relates to eyeglass mountings, and has for its object'to provide a mounting of the swing lens type in which the lens clamps are plvotally mounted on the ends of the nose bridge member to swing forward for the purpose of separating the nose grips, whereby the mounting may be placed upon and removed from the nose of the wearer by the swinging of the lens forward from their normal plane, thereby obviating the use of the finger grips or forwardly extending portion of the usual finger piece mountings.

It is found in practice that these finger grips or forward extending portions are in some cases quite objectionable, for instance they are in the way and often catch and become entangled in a womans veil, but by my improvedconstruction these projecting portions are entirely eliminated.

A further object of the invention is to provide means whereby the nose grips are capable of movement independent of the swinging action of the lens clamps, whereby the lenses are returned to a position in alinement with each other, and yet the nose grips are free to adjust themselves to a limited degree to noses of difi'erent shapes and sizes.

A still further object of the invention is to provide a simple and compact construction of the pivotal-joint and whereby a lens clamp member may be readily removed without disturbing the other members ofthe mounting.

The invention further consists in the provision of a tubular trunnion on the nose bridge member which the other members of the mounting may rotate and receive a bear- A still further object of the invention is to provide a stop whereby the lens clamps when under action of their spring return the lenses into alinement with each other.

The invention further consists in the provision of two separate springs operating independently, one upon the lens clamps and the other upon the nose grips.

With these and other objects in view, the

invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure lis an edge view of the mounting showing the lenses in their normal position in which they are in alinement one with the other; also indicating by center lines the forward movement of which the lenses are capable of separating the nose grips.

Fig. 2 is a greatly enlarged central longitudinal section through the pivotal joint at one end of the nose bridge.

Fig. 3 is a top view of this joint showing portions of the difierent members broken away to better illustrate the action of these members.

Fig. 4 is a section on line H of Fig. 2 showing the general arrangement of spring which acts upon the nose gripping member.

Fig. 5 is a section on line 5-5 of Fig. 2

showing the spring which acts upon the lens clamp.

Fig. 6- is a perspective view showing the lens clamp member with its two clownwardly projecting stop fingers, one to limit the forward and the other the backward movement swing of the lens.

Fig. 7 is a plan view of a portion of a nose gripping member.

Fig. 8- is a detail plan view of the enlarged end of the nose bridge.

Referring to the drawings, 10 designates the nose bridge member of my improved swing lens mounting, the ends of which bridge have enlarged flattened portions or lugs 11, see Fig. 8, and these lugs are each provided with a central upwardly turned tubular portion 12; and also a downwardly turned tubular portion 13, see Fig. 2, and an abutting finger 1e projects downwardly from the rear of this lug. A lens clamp member 15 is provided with lens straps and with a saddle 17 and is also provided with a forwardly extending lug 18. The under side of this clamp lug is provided with a downwardly extending portion 19 which fits over the upwardly extending tubular portion 12 of the nose bridge lug, thereby pro viding a space 20 between these lugs in which i a spring hereinafter described is housed. This clamp lug 18 is provided with a downwardly extending finger 21 which on gages the back side of the bridge and serves as a stop to cause the lenses to stop in alinement one with the other when forced back to normal position under tension of their respective springs.

This pad 18 is also provided with a downwardly extending finger 22 spaced from the finger 21 and which finger 22 is adapted to engage the bridge member on its forward side, to limit the forwardswinging motion of the lens.

The nose gripping 'meinber' 23 is p'roi ided with a flat lu'g 24 which is niouirt'edon the trunnion 13 'berieath'the bridge Mg 11 to rotate thereon, and this nose gripping dember is provicled'with a bendable "11111 25 and a pad '26 which is one of the two that; e0 1- ta'cfts with the sides of "the nose "to hold the mounting in position tl'iere'on.

This nose grip lug 24:, see Fig. 7, is provided with a'stop finger 27 which engages the portion 28 on the lens 'claii'ip to serve a double purpose: first, to limit the inward swing of the nose gripping pad and second, to provide ineaiis'whereby when the lenses are swung forward, their finger 27 is; engages by these nese grips nd teased to open ors'p'read apart so as to yieldingl permit the positioning of the mounting upon thei nose'o f the wearer.

I In order to provide a suitable tension ier this nose g1-ip, I have mounted 's'p'i'ral'ly coile'd spring 38 in the space 20, see Fig. 2, between the lens clamp lug and the nose bridge lug, the inner end 29 of this spring engages the nose bridge lug and its outer end 30 is hooked over the arm 23 of the nose gripping member, thereby normally pressing the grips inward"against the nose of the wearer.

In order to'secure all ofthese members together, I have passed screw 31 down through the tubular t aimiens, the lower end of the screw being threaded in the lower tru1'1'nio'n-13'and'anut 32 is threaded onto the extremity of the screw and is turned up into position 'to secu all er'the di'Iferentfinemtel-s 'wgeth'er. This are 32 is provided with a deep circular groove 33 infwhic'h is wound aco'il spring 34, one end 35 of thisspring enga'g'esth'e finger 14 ivhilethe ooposite end 36 engages the saddle 15 of the ens clamp thereby exerting a pressure upon the lens clan'il'bs to move "them backward until their stop linger brings up against the bridge member 10 at which time both olthe lenses are; in al-inenientone with the other.

By my improved Construction, it will be seen that in order to remove the lens clamp which is to be done quite often, it is simply necessary to turn back the screw 31 and slide olf the lens clanrp for inspectioiil or repairs. A Another feature as is herein illustrated-is that the two springs, one operating the nose grips and the other operating the lens clamps, are entirely separate and-independent of each other, thereby providing the nose grip with a motion independent of the action of the grip within certain limits without interfering with the perfect alinement of the lenses.

Having thus described one illustrative embodiment of my invention, I desire it to "be understood that the details of construction may be varied without departing from the spirit of the invention, the scope of which is defined by the appended claims.
